About Us
Meet the Team Behind Healthy Smiles by Dr. B
Experience, compassion, and a shared passion for creating healthier, happier smiles.
At Healthy Smiles by Dr. B, our story is built on a shared belief that dentistry should be personal, gentle, and rooted in trust.
Led by Dr. Denis Bourguignon (Dr. B) and Dr. Kristin Kalwara (Dr. K), our Hayesville practice combines decades of experience with modern laser technology and heartfelt care.
After years of practicing in Florida, Dr. B and Dr. K fell in love with the beauty and community of Western North Carolina.
In 2010, they began their journey toward opening a new kind of dental office — one where patients feel at ease, receive the latest in laser technology, and experience care that feels like family.
In 2017, they opened Healthy Smiles by Dr. B in Hayesville, NC, creating a space that reflects their values: compassion, integrity, innovation, and joy.
About Dr. Denis G. Bourguignon (Dr. B)
Known to his patients as Dr. B, Dr. Denis Bourguignon, DMD, brings over three decades of experience and a lifelong dedication to compassionate care.
Dr. B was born in the Belgian Congo (now the Democratic Republic of the Congo), where both his father and grandfather practiced medicine. After political unrest forced the family to flee in 1964, they eventually immigrated to Florida. His early life experiences shaped his empathy and appreciation for helping others.
Fluent in French and English, Dr. B earned his Doctor of Dental Medicine (DMD) from Temple University School of Dentistry in 1990. He practiced in Florida for 27 years before following his dream of living in the mountains of Western North Carolina, where he opened Healthy Smiles by Dr. B in 2017.
His approach combines old-fashioned service with state-of-the-art laser dentistry, offering patients comfort, precision, and confidence in every visit.
